Business Line of Credit: How It Works and How to Qualify
A business line of credit gives you revolving cash to draw, repay, and reuse for cash-flow gaps. Compare secured vs unsecured, rates, and how to qualify.
A business line of credit is revolving financing you draw on as needed, repay, and reuse — ideal for payroll gaps, inventory buys, and unpredictable short-term cash needs rather than one big purchase. You pay interest only on what you borrow, limits typically run from about $10,000 to $500,000, and rates depend on whether the line is secured and on your credit and revenue.
Most businesses don't fail because they aren't profitable — they fail because cash arrives later than the bills do. A business line of credit is the financial shock absorber built for exactly that timing problem: it sits open until you need it, costs little when idle, and gives you fast, reusable access to cash. Here's how it works, what it costs, and how to qualify.
The short version
Use a business line of credit for recurring or unpredictable short-term needs — not long-term assets. You pay interest only on the balance you draw, and repaid capacity becomes available again. Secured lines carry lower rates and higher limits; unsecured lines fund faster with lighter requirements but cost more. Match the line to a genuine timing gap, not a cash-flow problem you should fix at the root.
How does a business line of credit work?
A lender approves a maximum credit limit. You draw any amount up to that limit, and interest accrues only on the outstanding balance — not the full line. As you repay principal, that amount becomes available to borrow again, which is what makes the facility revolving. There's no need to reapply for each new need the way you would with a term loan.
That structure is the whole point. A term loan hands you a lump sum you start repaying (and paying interest on) immediately, which fits a single defined purchase. A line of credit is optionality you keep on the shelf: you're buying the ability to move fast, not financing a specific asset today.
Draws usually hit your business bank account within a day or two, and many lines let you draw through an online dashboard or even a linked card. Repayment terms on each draw commonly run 6 to 24 months, and lines are typically reviewed and renewed annually.
What can you use a business line of credit for?
A line of credit shines for working capital — the everyday cash that keeps operations running:
- Covering payroll during a slow month or while you wait on receivables
- Buying inventory ahead of a busy season
- Bridging the gap when a large customer invoice is 30, 60, or 90 days out
- Handling an unexpected repair, tax bill, or opportunity that won't wait
- Smoothing seasonal swings in revenue
It is a poor fit for large, one-time investments like buying real estate or funding an acquisition — those belong on a long, low-rate facility such as an SBA loan. Financing a decade-long asset on revolving credit means paying a higher rate on money you'll carry for years.
Secured vs unsecured: which line fits?
The biggest structural choice is whether the line is backed by collateral.
| Factor | Secured Line | Unsecured Line |
|---|---|---|
| Collateral | Receivables, inventory, or cash | None specific (personal guarantee) |
| Typical limit | Higher — often $100k to $500k+ | Lower — often $10k to $250k |
| Typical rate | Lower | Higher |
| Funding speed | Slower — collateral review | Faster — as little as 1-3 days |
| Best for | Established businesses, larger needs | Newer businesses, fast flexible access |
Rates and limits are guidelines, not guarantees
Actual pricing, limits, and terms vary widely by lender, your credit profile, revenue, and time in business. Treat every range here as a planning starting point, not a quote. Unsecured lines from online lenders can price well above bank rates in exchange for speed and lighter requirements.
Many businesses start with an unsecured line to get moving, then qualify for a larger, cheaper secured line as they build revenue history and business credit.
How do you qualify for a business line of credit?
Lenders weigh a handful of factors. Strengthening these before you apply improves both your odds and your rate:
Time in business
Online lenders often approve at six-plus months of operating history; banks typically want two years or more. Longer history signals stability.
Revenue and cash flow
Consistent monthly deposits matter more than a single big month. Lenders want to see that repayment fits comfortably inside your normal cash flow.
Business and personal credit
Both are usually reviewed, and most lines require a personal guarantee. Cleaning up your business credit and personal report first can move your rate.
Existing debt
Lenders assess your total debt service. If you already carry loans, be ready to show the combined payments still leave room.
To see how a draw's monthly cost changes with rate and repayment term, run a few scenarios before you commit.
Estimate your monthly payment
A representative estimate at 9%–24% APR. Actual rates and terms vary by business and product.
Line of credit vs credit card vs term loan
Pros
- Draw only what you need; pay interest only on the balance
- Reuse capacity as you repay — no reapplying
- Funds in days, ideal for timing gaps and emergencies
- Lower rates than most business credit cards
Cons
- Higher rates than an SBA or bank term loan
- Limits usually too small for a major acquisition
- Variable rates plus possible draw or maintenance fees
- Easy to lean on instead of fixing root cash-flow issues
A business credit card is convenient for small, everyday purchases and earns rewards, but rates run higher and cash advances are expensive. A term loan is cheaper for a large, defined, one-time cost. The line of credit lives between them: cheaper and more flexible than a card, faster and more reusable than a term loan.
